点云数据转换文件。可以将PCL转换为PLY文件，反之亦然。其中用到了点云库PCL的代码。(Point cloud data file conversion. PCL can convert PLY files, and vice versa. Which uses a point cloud library PCL code.)

说明：  三维人物绘制，使用DirectX的ID3DXAnimationController接口实现三维人物绘制，其中包括骨骼蒙皮技术。注意：编译时一定要将Resource文件夹拷贝到Debug或Release目录下。(Drawing three-dimensional characters, the use of the DirectX interface ID3DXAnimationController drawing three-dimensional figures, including skinned mesh technology. Note: When the compiler must Resource folder are copied to the Debug or Release directory.)

计算机图形学中的shadow mapping程序，与网上其他代码不同，作者实现了对带有纹理的场景的阴影绘制.(Shadow Mapping Code in Computer Graphics.And it s for textured scene.)

说明：  D3D 的入门程序，包括初始化D3D编程环境和初始化窗口(D3D init program)

osg粒子子系统例子,一个是简单的粒子系统，另一个是烟(the example of particle sysytem in OSG)

3维圆柱面，可以上下左右不同视角观看，使用上下左右方向键操作(3D Cylinder)

说明：  四叉树（lod）实现地形三维可视化的程序，内有代码和数据(quadtree (incomplete) 3D terrain visualization procedures, which have code and data)

说明：  利用VTK实现的一个可以不停旋转的球体，不需要交互(VTK can be used to achieve a continuously rotating sphere, does not require interactivity)

利用分形和混沌理论，生成十分精美的2维图形。有多种参数可以对图形进行控制。(use fractal and chaos theory, generate very attractive two-dimensional graphics. A number of parameters can control graphics.)
